time staying in alpine route

Hi,
We will travel in the alpine route on 2017.04.30.
We would like to know how long we can stay in every station (approximately)
as we want to go by train(if it is possible) to takayama in the same day in the evening.
Thanks for your answer
Ita.

Depends on the start location.

Dear Sir,
Thanks for your fast reply.
We will come early morning from Matsumoto with the train to Shinano Omachi and will begin in from Shinano Omachi.
we will finish our tour in Alpine route at Tatayama station and would like to take the train in the same day to Takayama.
i would like your advice regarding the time table of every station
and the plan of this day.
waiting for your response.

thank you very much.
Best Regards

Have a look at the Alpine Route website, it has a lot of helpful information.

This link includes Plan your Schedule, which will help you plan your day.

Here is a very detailed blog post on the same alpine route. Although its the opposite direction of your intended route, it still gives you a good idea of how much time to spend at each station and what to look out for.
